They seem to have some pretty nice tube amps....?
Just recently I listened to the 502B and 302B, being fed by the Jolida JD-100 cd player. Both sounded very good although the 502 had slightly more bass. I'ld be happy with either one of them...both are well worth the $$$.
They are an excellent buy, good value.
I've enjoyed the ones I own and prefer them over quite a few more expensive amplifiers that I've tried. Jolida puts tonality high on their list and they do that well. Excellent customer service/support too.
With any tube amp, make sure your speakers compliment the amp or the combination can disappoint. Tube amps usually have high output impedances and it's usually better to have easy to drive speakers that don't dip below 4 ohms or so.
